As disclosed in the accompanying *drawings, i denotes the shank ofiny iinpr'oyed `n*renehhaying;produced'in itsopposite sides,

the longitudinally directedgroovesiopen 'at one `end of'such shank while the opposite ex- .trennty ot the shank Ais pioyidedfn'ith the stationary jan-3, Wit-h Which is adapted to coa'ct the cla'nlping or sliding jaw l'inounte'd for endwise lmovement upon theshank ,1.

The "janv 4 is proyided with a 'loorethrongh which the shank lisadapted Vto:bedirected and the opposite side Walls of such opening yor bore being provided With theinwa rdly directed tongues or shoulders- G va'dz'rp'ted to project Within the grooi'es'or channels 2 produced-1n the shankl whereby itfwill he perceiv'ed 'that the jaw 4 is maintained 'substanytially against lateralor' transr'er'selinovenient. T he .forwa'rdface of the jan' e' 4is proyided'n-'ith the transverse'slotintersecting the longitudinally directed recess S produced inthe outer face of the'jaw stand' into which is adapted to be projected the'thre'aded shank-Q- such threaded shank Qfbeing engaged bythe adjusting nut orv Wheel il()l 0perat-ively positioned within lthe .slot 37,' the outersurface or periphery of such nut or 'Wheel l0 being milled or serrated,for a purpose" which v is believed' to bev self-evident. The outer portion of the recessB'-, :as indicated at '1L isenlargred in order to accom-l modate the head 12 of the threaded shank, 9, which head l2 has its outerextreniity. projected exteriorly of the jan*4 and has its outer end roundfalgas indicated at 14.*@

- The'inner longitudinal edge ofthe-shank l is providedwith the series of teeth-15 eX- vtending a predetermined distance longitudina'lly thereonuth the -inner tooth thereof spaced a jn'edeteriuined:distance'froin 'the stationary and surrouinling` thefshank l' the sleeife iti. l'theflxore rwhereofbeing grenier than the u-'idthoflthe shank. l, asas 'clearly'Y :shown in VFig.- .lg' one Wallffsueh sleeve heiujrprovided with ak seri'eso teeth 1S adapted `to interlock ywith. the vteeth -15 1n order tnuruaintaiu 'thesliding-jan?e against nroafenfrcrrellenigit1ldinally; of the shank 1,; as

willhereinafter he more fully set fortln' independently ofthe adjustment of such jaw 4 as aliorded by the 'threaded shank 8 land its concomitant parts. The teeth 18 arenormally maintained in mesh with Ithe teeth 15 v through the tension exerted by the double 'leaf spring 19 suitably anchored, as at 20, to the outer end of the sleeve 16 intermediate its length and having. its extremities contacting with the unobstructed or outer edge of the shank 1, as is clearly shown in Fig. 1,

it beingvreadily perceived 'that the teeth 18 freed from the teeth by forcing 'ive 16 against the tension of the hich may be done with convenienc'e vd facility by a 'digit of the hand graspingthshank 1. v

WVhile thefzteethj 18 may be produced directly -uponthe sleeve 16, I prefer tohave may be e@ a.

the same formed on a removable block or insert 21, particularly illustrated in Fig. 3,

which block or insert 21 beingproduced inits face with the transverse open ended slot o-r groove 22 adapted t0 c'oact with a similarly disposed inwardly directed shoulder or i tongue 23 produced on the inner wall of the sleeve 16 whereby it will be readily perceivedthat such` blocker insert 21 is properly maintained in operative position. To

' further assure against displacement of this block or insert 21, I fiid it of advantage to provide at one end thereof the extension 24 provided with openings 25 through which suitable anchoring means 26 may be directed, such anchoring means also coacting with the sleeve 16, which sleeve, of necessity, must be provided with openings adapted to register with the openings 25 of the block or insert 21 when the same is in assembled position. By use of the block or insert 21, itv

tremity provided with the perforate spaced ears 28 adapted to accommodate therebetween the projected extremity of the head 12, such ears and head having directed therethrougha suitable pin or pintle 29 whereby it will be readily perceived that a pivotal engagement is created between the lever or eX- tension 27 and the head 12 whereby the sleeve 16 may be operated with greater convenience and facility whereby it will be perceived that the inclination of the extension or lever 27 is such as to assure an effective locking engagement between the teeth 15 and 1'8 When the improved monkey-wrench is in actual use.

In order that the pintle` or pin 29 maybe f substantially freed from the pressure or strain created when the device is in operation, I find it of advantage to have the end of the extension or lever 27 between the ears 2S, as indicated at 30, concaved to firmly abut the rounded end 11 whereby it will be readily perceived that the strain or pressure, when the wrench is in use, is upon the eX- tension or lever 27 and the head 12 substantially independent or free of the. pin or pintle 29. l

In order to maint-ain the shank 9 in operative position, I find it of advantage to provide in a face of the head 12 adjacent the inner end portion thereof, the elongated lon gitudinally disposedv recess 31 into which projects a finger 32, operating in a manner which is believed tol be self-evident.

From the foregoing description, it is thought to be obvious that a monkey wrench constructed in accordance with-an embodiment 'of my invention is of an extremely simple and comparatively inexpensive nature and is particularly welll adapted for use by reason of the convenience and facility with which it may be assembled and-by reason ofthe effectiveness with which it performs its various functions, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not Wish to be understood as limiting myself to' the precise arrangement and formation of 4 the several parts herein shown 1n carrying out my invention in practice.

I claim:

1. A device of the character described including a shank having teeth on one edge and a fixed jaw, a'movable jaw slidably mounted upon the shank, a sleeve slidably mounted upon the shank below the movable jaw, the bore of the sleeve being in eX- cess of the width of the shank, such sleeve being provided with teeth adapted to engagev the. teeth of the shank, means for maintaining the teeth of the sleeve normally in engagement with the teeth of the shank, an elongated member carried by the movable jaw', an extension carried by the sleeve in pivotal engagement .with the elongated member, and means coactingwith the movable jaw and the elongated member whereby such n'lovable jaw may be moved endwise of the shank independently of the movement afforded when the'teeth of the sleeve and the teeth of the shank are disengaged. v

2. A device of the character described including a shank having teeth on one edge and a fixed jaw, a movable jaw slidablyl mounted upon the shank, a sleeve slidably mounted upon the shank below the movable jaw, the bore of the sleeve being in excess of the width of the shank, such sleeve being provided with teeth adapted to engage the teeth of the shank,y means for maintaining the teeth of the sleeve normally in engagel of the shank ae disengaged iudinnlly disposed channel ment Wiel elle 'tee-ll of ille shank, aa elon gated member earl'eil by,7 ille nllovable im', an exenson eeyrleil by the efe in pvot-el engagemelli;l wil-la lle eleagaecl member, and means eoaeng lill the mov e jaw nel the elongated. 3. .meer whereb suoli movable. aw may be aoved einle'lee of the sllelli ndepeedenly of elle l allolelefl n n the 'fie-ete of 'alle sleeve all lle teeth adapted to melll; lill llle eetll of elle shank, menne foi* maintaining suele block in operative Qoson, means. for mainainlng Yelle leetll of the bleek normall merli; Yvill elle "eelw of the ella all elengelefil member cal, ell by IElle Dow/able jaw, an ex'euslon earned by the le pivote engagement all ille elolu ed )member am .11S eoaeing ell elle mmable jaw a ille elongatea memle whereby saell eleva jaw may be moved enclwlse of lle ellanl; *lependealy ei the mofemenrall'orilefgl when meunel upon 1n engage 'ille eeh of the bleek and the teeth of the elell: disengaged.
